Integrable Deformations of the Breitenlohner-Maison Model from 4d Chern-Simons Theory
Meer Ashwinkumar, Matthias Blau
We derive integrable deformations of the 2d Breitenlohner-Maison (BM) sigma model that describes the stationary, axisymmetric sector of 4d general relativity, as well as higher-ran…
Gauge Theory, Hyperbolic Geometry and Virasoro Coadjoint Orbits
Matthias Blau, Donald R. Youmans
It has long been known that the moduli space of hyperbolic metrics on the disc can be identified with the Virasoro coadjoint orbit $\mathrm{Diff}^+(S^1) / \mathrm{SL}(2,\mathbb{R})…
On the Evaluation of the Ray-Singer Torsion Path Integral
Matthias Blau, Mbambu Kakona, George Thompson
There are very few explicit evaluations of path integrals for topological gauge theories in more than 3 dimensions. Here we provide such a calculation for the path integral represe…
3 Definitions of BF Theory on Homology 3-Spheres
Matthias Blau, Mbambu Kakona, George Thompson
3-dimensional BF theory with gauge group (= Chern-Simons theory with non-compact gauge group ) is a deceptively simple yet subtle topological gauge theory. Formally, its pa…
Massive Ray-Singer Torsion and Path Integrals
Matthias Blau, Mbambu Kakona, George Thompson
Zero modes are an essential part of topological field theories, but they are frequently also an obstacle to the explicit evaluation of the associated path integrals. In order to ad…
Chern-Simons Theory on a General Seifert 3-Manifold
Matthias Blau, Keita Kaniba Mady, K. S. Narain +1
The path integral for the partition function of Chern-Simons gauge theory with a compact gauge group is evaluated on a general Seifert 3-manifold. This extends previous results and…
